The most shattering story for the former Arkansas governor is an AP report about Huckabee’s record on A.I.D.S., which says he once promoted isolating patients from the public, opposed federal funding for research and said homosexuality is a health risk. This report may truly hurt his candidacy, not because it is necessarily any more controversial than releasing a convicted rapist, but because it runs contrary to his message of tolerance. Before this, Huckabee has managed to seem conservative, but kind.
